1. A method for adjusting a protocol data unit (PDU) session comprising:
obtaining, by a second core network device, a first message from a first core network device, wherein the first message comprises a first parameter and a network resource status of a first application;
sending the first message to a terminal device to instruct the terminal device to obtain a measurement result of the first parameter;
obtaining the measurement result from the terminal device;
sending the measurement result to the first core network device;
obtaining a second message to instruct the second core network device to configure, based on the measurement result, a second parameter to adjust the PDU session;
obtaining a fourth message from a third core network device, wherein the fourth message comprises at least one of a first application identifier or a second time period; and
retaining the PDU session when the fourth message includes the first application identifier.
